Abstract
A flexible printing subsystem is enabled with a printer filter pipeline. A configurable and arbitrary number of printer filters forming a printer filter pipeline are applied to files that are to be printed. In a described implementation, the printer filter pipeline may implement enhancement features and conversion functions as determined by the individual printer filters forming the printer filter pipeline. The printer filter pipeline is established in accordance with a printer filter configuration file. The printer filter configuration file stipulates a printer filter order and includes a printer filter entry associated with each printer filter to be part of the printer filter pipeline. Each printer filter entry identifies the associated printer filter by name and enumerates the interfaces thereof. Printer filters may be adjacently linked in a printer filter pipeline when their mating interfaces match.
